Fertilizing Ice Plant

Ice plants or delosperma are flowering perennials native to South Africa. These plants are succulents, so they are not heavy feeders. Newly planted ice plants do not need fertilizer, but mature ice plants are fast growers, and applying a light feeding keeps these perennials healthy and strong and encourages prolific blooming.  


How to Fertilize Ice Plant

Slow-release fertilizers work well for ice plants and should be applied at the base of the plant. Water dissolves the fertilizer so that the roots can absorb the nutrients slowly over the growing season. Delosperma does best in soil with a neutral pH, so avoid using fertilizers that alter the pH.  

Best Time To Fertilize Ice Plant

Fertilize ice plants once or twice annually. Ice plants are succulents and can benefit from a light feeding of compost or a formula for succulents, but they can become leggy if overfed. Apply fertilizer in the spring and again by midsummer to support new growth.

Best Fertilizer For Ice Plant

Use a slow-release fertilizer since ice plants require infrequent feedings. Slow-release products release nutrients over an extended time, providing continued support. Fertilizers formulated for use on blooming succulents, such as The Grow Co Succulents & Cactus Plant Food will support the roots, foliage, and flowers for well-rounded support. A formula with a balanced NPK ratio is about right.

Ice Plant Fertilizing Tips

  • Do not fertilize newly planted ice plants
  • Fertilize ice plants in the spring and midsummer
  • Use a slow-release fertilizer, formula for succulents, or layer of compost
  • Water after applying fertilizer to dissolve the granules and protect the roots from fertilizer burn


-Always wear protective gloves and a face mask when handling chemical fertilizers.

-Closely follow all directions and storage guidelines that are on the fertilizer label.
